This sounds like a very sensible approach and is quick and easy to try out
using tricontour/tricontourf. You may have to use a very small positive
value for the contour level rather then zero to get what you want.

Yes, it is clear what you are trying to do. I think that you shouldn't be
concerned with the triangulation, Delaunay or not, as this is at too low a
level for what you are attempting. Stick to the high-level data analysis
and presentation functions like tricontour and ignore details of the
underlying triangulation. If you are having to manipulate a triangulation
then you are becoming a computational geometrist - it is a completely valid
and interesting thing to do but is probably taking your attention away from
your real work.
